Replying to Does MIPS work while wearing a beanie or Balaclava?

Generally speaking, Ive always worn my helmets without a genie or balaclava or just a buff. however, I just bought a Smith Maze and spent the extra $30 on a MIPS equipped version. are the effects of that layer canceled out by wearing a beanie or slick balaclava because the low-friction Material would slide on the fabric of that? Or is it basically going to act the same way as it would on hair? Any insight would be helpful K+ to anyone with something useful to say.
